QUOTE: Starting with the Obsidian series, Corsair has systematically released a chassis to tackle almost every segment. With most of the segments covered, Corsair has rethought the ATX case and has released something a littleâ¦ different. Launching at the top of the Carbide series (designed to be focused on performance and high-end features, while still being accessible to every builder), the Carbide Air 540 cube-style computer case brings a unique option to the series. Benchmark Reviews tests to see if itâs worth the $139.99 price of admission.
